Berlingo faults lighting up, injectors

[LImerickDave]

    Hi all. I have a 2008 berlingo, 220,000 km. Engine light on. The problem is the starter turns but the engine won't start. After a few attempts it might start, even then I need to accelerate to keep engine going. The rough idle usually stops after a drive. Once engine is warmed up it's ok. Once I switch erase all the faults the car runs perfect for a day or 2 , then engine comes on and same issue. I've replaced egr and new heat plugs recently. 
Faults are 1351, 1197, 1366, 1368, 2148. Thanks

Electrical fault on the injector harness maybe? Could be chafed through.

Is there a way to diagnose this? Thanks for reply

Short circuit between two injector pins that code says...

you'd need a multimeter and do some resistance testing. See what a normal injector shows between the pins in ohms, then check all 4 with no plugs connected. Are any standing out as different?

Then see if any injector harness plug shows a short circuit between the plug pins. That distinguishes between a bad injector and the harness itself.

All tests with the ignition off.

Do not crank the engine with any injector disconnected, it buggers the injectors.

See what you find, and post back.
